The present invention relates to a stopper for a flip-up gate, which is used to prevent the lower end of the door from hitting the ground when closing the entrance by the flip-up gate. (Prior Art) Conventionally, as stoppers for such a flip-up gate, there are, for example, those shown in FIG. 6 and FIG. 7, respectively. The flip-up gate partially shown in FIGS. 6 and 7, respectively.
Reference numeral 51 denotes a pair of arms 52 (52) (one of which is shown in the figure) whose one ends are pivotally attached to opposite columns (not shown).
The door 53 is fixed to the other end side of the arm 52, (5
The door is opened and closed by turning the door 53 along with the vertical movement of 2).
Shows a state in which the door is opened by opening the door, and FIG. 7 shows a state in which the door is closed by closing the door 53. A stopper 61 provided on the flip-up gate 51 shown in FIG. 6 has a leg portion 63 having one end fixed to the lower end of the door 53 (the left end in FIG. 6) and the other end fitted with a cushioning member 62. ,
The leg portion 63 is fixed so as to project downward from the lower end of the door 53 (leftward in FIG. 6). On the other hand, the stopper 71 provided on the flip-up gate 51 shown in FIG. 7 has a horizontal shaft 72 provided at the lower end of the door 53 and in the width direction of the door 53.
And a rotation block 74 rotatably supported on the horizontal shaft 72.
And a leg portion 73 having one end fixed to the rotating block 74 and the cushioning member 75 attached to the other end. When the door 53 of the flip-up gate door 51 is positioned above, block
The 74 rotates about the horizontal shaft 72, and the leg portions 73 are oriented in the vertical direction. (Problems to be solved by the invention) However, the stopper for the conventional flip-up gate described above.
In the case of the stopper 61 shown in FIG.
Since the leg portion 63 is fixed in a state of protruding from the lower end of the door 53 to the lower direction of the door 53, when the door 53 pivots as the arms 52, (52) rotate, a stopper 61 is provided. However, the stopper 61 has a problem that it cannot be said that the stopper 61 does not hinder traffic because it extends further to the road side (left side in FIG. 6) than the lower end of the door 53. Further, in the case of the stopper 71 shown in FIG. 7, although the problem of the stopper 61 described above can be solved, if the leg portion 73 is inclined with respect to the vertical direction when lowering the door 53, When the cushioning member 75 provided on the leg portion 73 comes into contact with the ground, the leg portion 73 may rotate about the horizontal shaft 72 in the direction of the road side or the site side indicated by the arrow in FIG. is there. Further, in a state after the door 53 is lowered to bring the leg portion 73 into contact with the ground without the above-described rotation of the leg portion 73, for example, the arm 52, (52) is pushed down and the arm 52,
When a vertical force is applied to (52), the leg 73 may rotate about the horizontal shaft 72 in the direction shown by the arrow in FIG. 7, and as a result, the lower end of the door 53 may be rotated. However, there is a problem in that there is a risk of scratches coming in contact with the ground and damage to the stopper 71 itself. (Purpose of the Invention) The present invention was made by paying attention to the above-mentioned conventional problems, and when turning the door of the flip-up gate,
A stopper for the flip-up gate that does not obstruct traffic and eliminates the risk of the bottom edge of the door coming into contact with the ground and scratching when the door is closed or in the closed state. It is intended to be provided.

[Constitution of device]

(Means for Solving the Problem) This invention is a flip-up provided with a door that is supported by a pair of arms pivotally attached to opposing columns and that pivots and opens and closes as the pair of arms pivots in the vertical direction. In a gate, a rotating body provided with a horizontal shaft provided on a strut-side finding surface of the door, a leg portion rotatably supported on the horizontal shaft at one end side, and abutting against the ground at the other end side when the door is closed; It is equipped with a vertical state holding part that regulates the rotation of the leg part to the door side when closing, and holds the leg part in a substantially vertical state with respect to the ground. It is characterized in that it is set from the line to the strut side and that the leg portion is arranged so that the axis line of the leg portion can pass between the door and the horizontal axis when the door is closed. The stopper of the flip-up gate is used as a means for solving the above-mentioned conventional problems. ing. (Operation of the Invention) Since the stopper for the flip-up gate according to the present invention has the above-mentioned configuration, when the arm is pivoted in the vertical direction and the door is pivoted in the vertical direction, the leg portion of the pivoting body is In addition to being supported by the pillar side (site side) of the door, the legs are always oriented almost vertically while rotating around the horizontal axis, so the pillar is more than the lower end of the door. Since it does not project to the opposite side (road side), there is no risk of obstructing traffic. In addition, when the door is closed by the door and in the closed state, the center of gravity of the rotating body having the legs is set to the pillar side from the vertical line passing through the axis of the horizontal axis.
Since the leg axis passes between the door and the horizontal axis, a large moment is generated in the leg about the horizontal axis toward the door side. The rotation of the legs is regulated by the vertical state holding portion and is held substantially vertical to the ground. Therefore, the leg portion can be placed on either the pillar side (site side) or the door side (road side). Will not rotate to the side of, and the lower end of the door will not touch the ground. (Example) Hereinafter, this invention is demonstrated based on drawing. 1 to 5 show an embodiment of a stopper for a flip-up gate according to the present invention, and FIG. 4 shows the lower left side of the figure as the road side, except for FIGS. 4 and 2. Other figures show the left side of the figure as the road side. That is, as shown in FIG. 4, the flip-up gate 1 is
A door 4 is fixed to the other ends of a pair of arms 3 and 3, one ends of which are pivotally attached to opposite struts 2 and 2 installed on the ground E, and by pivoting the arms 3 and 3 in the vertical direction, The door 4 is swung up and down to open and close the doorway. Then, the flip-up gate 1 is provided with a fourth door 4
When the door 4 is closed as shown by the solid line in FIGS.
A stopper 10 is provided to prevent the lower end of the ground from contacting the ground E. The stoppers 10 are provided on both vertical frames 4b, 4b of the door 4, respectively. As shown in FIGS. 1 and 2, the lower end of the vertical frame 4b of the door 4 is in a state in which the door 4 is located below. Side and the pillar 2 side (the right side in FIG. 1 and the site side), the shaft support metal fitting 11 having a substantially U-shaped planar shape provided on the finding surface 4a, and the lateral side supported by the shaft support metal fitting 11 The shaft 12 is provided with a rotating body having a rotating block 13 supported by the horizontal shaft 12 and a leg portion 14 provided on the rotating block 13. The shaft supporting fitting 11 has a bottom 11a and a door 4. It is fixed by screwing screws 16, 16 into the back plate 15 from the bottom 11a side while sandwiching the strut 2 side (site side) finding surface 4a of the door 4 with the back plate 15 provided inside the The horizontal shaft 12 is provided in a state of penetrating the wall portions 11b, 11b of the shaft supporting fitting 11 which face each other and in parallel with the door 4. The rotating block 13 includes wall portions 11b, 11 of the shaft supporting fitting 11.
It is rotatably supported by the horizontal shaft 12 between b, and has a flat leg mounting portion 13a at its rotating end. The leg 14 is substantially U-shaped in this embodiment,
The branch-shaped end portion is embedded and fixed in the leg mounting portion 13a of the rotating block 13 in a substantially vertical state, and the bent end portion is fitted with a cushioning member 18 that abuts against the ground E. Is
Both branch portions are fixed so as to be parallel to the door 4 located below. In this case, the rotation block 13, the leg portion 14 and the cushioning member 18
As shown in FIG. 1 and FIG. 3, the position of the center of gravity G of the rotating body is composed of a vertical line passing through the axis of the horizontal shaft 12 to the side of the supporting column 2 (in this embodiment, diagonally below the horizontal shaft 12). By setting it so that when the door 4 turns, the leg portion 14 is always directed vertically or slightly toward the door 4 side from the vertical direction, so that the leg portion 14 of the stopper 10 is closer to the road than the lower end of the door 4. I try not to overhang it. Further, in this embodiment, the position of the center of gravity G of the rotating body is set as described above, and the axis of the leg portion 14 passes through between the door 4 and the horizontal shaft 12 located below. By arranging 14 to generate a larger moment in the direction of the door 4 about the horizontal axis 12 in the leg portion 14 when the door 4 is located below and in the state where the door 4 is located below. As a result, the leg 14 tends to rotate toward the door 4 due to this moment, and the leg 14 is supported by the pillar 2.
It is designed to prevent rotation to the side (site side). Further, the stopper 10 regulates the rotation of the leg portion 14 to the door 4 side, which has generated the moment in the door 4 side direction, by setting the position of the center of gravity G of the rotating body as described above. It has a vertical state holding portion for holding it in a state substantially vertical to the ground E, and in this embodiment, the bottom portion 11a of the shaft support fitting 11 is a vertical state holding portion,
The bottom portion 11a receives the screw 17 provided on the surface of the rotating block 13 near the leg mounting portion 13a and on the door 4 side, so that the leg portion 14
Is prevented from rotating toward the door 4 side due to the moment, so that it is substantially vertical to the ground E. Next, the operation of the stopper 10 from the state in which the door 4 of the flip-up gate 1 described above is positioned downward to the time when the door 10 is closed will be described. First, from the state shown by the solid line in FIG. 3 and the phantom line in FIG. 5, that is, the state in which the door 4 is located above, the arms 3, 3 are rotated downward by a driving means (not shown) or a manual operation. When 4 is swung downward, the stopper 10 causes the vertical frame 4b of the door 4 to be found on the strut side during the turning.
In addition to being provided on the horizontal axis 4a, the position of the center of gravity G of the rotary body composed of the rotary block 13, the legs 14 and the cushioning member 18 is set on the horizontal axis
Since it is set from the vertical line passing through the axis of
By rotating the leg portion 14 about the horizontal shaft 12 via the rotation block 13, the leg portion 14 is always oriented vertically or slightly toward the door 4 side from the vertical direction. Since it does not project to the road side, the door 4 can be lowered without obstructing traffic. Then, when the door 4 descends and the legs 14 of the stopper 10 come into contact with the ground E through the buffer member 18 as shown by the solid lines in FIGS. 1, 2, 4, and 5, the doorway Is closed by the door 4. At this time, stopper 10
The leg portions 14 of the base plate contact the ground E in a state of being oriented almost vertically, and in this embodiment, the axis lines of the leg portions 14 are the door 4 and the horizontal shaft.
Since the positional relationship is such that it passes between 12 and 12, in combination with the setting of the position of the center of gravity G as described above, a larger mameton in the direction of the door 4 side is generated in the leg portion 14. In this case, the screw 17 provided on the rotation block 13 does not rotate to the side of the column 2, and further, the screw 17 provided on the rotation block 13 abuts on the bottom portion 11a as the vertical state holding portion of the shaft support fitting 11 to maintain the vertical state. Therefore, the leg portion 14 does not rotate further to the door 4 side due to the moment. Also, when the door 4 is located below, the arms 3,
Even when the vertical force is applied by pushing down 3 or the like, as described above, the leg portion 14 is provided on the door 4 side and the support column 2 side.
Since the rotation is restricted and the vertical state is maintained on any of the sides, the door 4 does not come into contact with the ground E and get scratched. The stopper 10 for the flip-up gate according to this invention
The detailed configuration of the above is not limited to the above-described embodiment, and for example, the vertical state holding unit may be used as the vertical support surface 4a of the door 4.
It is also possible to provide it at the lower end of.

[Effect of device]

As described above, since the stopper of the flip-up gate according to the present invention has the above-described structure, when the door of the flip-up gate is rotated, the leg portion is stretched on the side opposite to the pillar from the lower end of the door. Since it does not come out, it does not interfere with traffic, and when the door closes the door and when it is closed, the leg has a large moment to the door side centered on the horizontal axis, Since the vertical state holding portion regulates the rotation of the leg portion toward the door side beyond the vertical state, the leg portion does not rotate on either the door side or the column side. The very good effect that there is no possibility that the lower end of the door comes into contact with the ground and scratches is brought about.
